I-94 and Sheyenne Street Interchange Improvement Project (2018 - 2019)
In 2018 and 2019, NDDOT is overseeing the complete reconstruction of the Interstate 94 and Sheyenne Street interchange in West Fargo. The new Modified, Single Point, Urban interchange design will be a first for North Dakota interstate system.
New Modified, Single Point, Urban Interchange Design:
- Moves double lanes of traffic through one stoplight in the middle of the interchange on the north and south sides
- Northbound traffic will never stop at a traffic signal when entering Sheyenne Street
Work Zone Limits:
- I-94 – half mile east and west around Sheyenne Street Interchange
- Sheyenne Street – Christianson Drive to E Beaton Drive
Project work began in early May and has entered into winter suspension. Work on the bridge over the diversion in segment two will occur during the winter months with the rest of the work on Sheyenne Street and interchange to resume in the spring 2019.
Prep work for the project began in September 2017 by building the needed interstate cross-overs on I-94. This reduced six weeks from the construction timeline for 2018 project work. These cross-overs are used to help shift traffic to head-to-head on one side of the interstate for two-years of project work.
Two driving lanes for eastbound and westbound I-94 are now open through the Sheyenne Street interchange. Speeds reductions are removed and posted speeds returned to 55 mph.
With the I-94 off-ramps back to how they originally operated with one for north traffic and one for south traffic, to travel:
- South on Sheyenne Street (346-A): drive over the I-94 bridge to use the new westbound loop ramp to only travel south
- North on Sheyenne Street (346-B): use the new westbound off-ramp to only travel north. Drivers are not able to turn left to travel south from this ramp any longer.
To help reduce confusion in traffic control after the traffic shifts, signal heads and signal light phasing for the off-ramp was adjusted to support drivers. A message board has been placed between Veteran’s Blvd and Sheyenne Street to give drivers notice which exit to take just prior to the interchange ramps.
All interchange ramps are open for entering and exiting interstate traffic.
Single lane of Sheyenne Street traffic for north and south remains under the I-94 bridges between East Beaton Drive to Christianson Drive.
Remaining 2018 construction activity:
The two-year North Dakota Department of Transportation (NDDOT) Fargo District I-94 and Sheyenne Street interchange reconstruction zone will soon enter winter suspension after crews:
- Install: final striping and winter suspension traffic control signs and devices
- Complete: grading and earthwork for widened Sheyenne Street roadway
The project work will support increased density, address safety concerns, upgrade the rural roadway, ease congestion, and add multimodal facilities to the area. Work will span over two years:
- First year: Westbound Sheyenne Street bridge will be reconstructed; the North and South Sheyenne Street traffic will drive on the same roadway between E Beaton Drive to Christianson Drive
- Second year: Eastbound Sheyenne Street bridge will be reconstructed, on and off ramps will be constructed or lengthened, and most of Sheyenne Street will be reconstructed between E Beaton Drive to Christensen Drive
Project will Reconstruct/ Install/ Upgrade:
- Two new bridges on I-94
- Wider underpass for Sheyenne Street
- Construct a modified single point urban interchange and additional loop ramp to improve traffic flow
- New retaining wall
- Improved pedestrian facilities – Box culverts under ramps and shared use paths
- Traffic signals and street lighting
- Improved drainage – upgrades to lift station, storm sewer and city utility
NDDOT has funded the entire interchange project with state and federal funds. Interchange project cost is $19.1 million.
- Federal: $13.1 Million
- State: $5.5 Million
- City: $.5 Million (Drainage)
Adjacent Project Work:
The City of West Fargo is overseeing the reconstruction project from 13th Avenue W to 40th Avenue W. Sheyenne Street work zone will stretch for about 2 miles.
Segment 1: Sheyenne Street from 13th Avenue W. to 19th Avenue W. is now open in reconstruction project limits. The new road includes two lanes in each direction and a center turn lane to ease congestion and safety concerns. There will be some lane closures during December and February for street light and traffic signal installation.
Segment 2: Currently, 26th Avenue W intersection is closed at Sheyenne Street as crews reconstruct the intersection. At 32nd Avenue traffic is head-to-head on the north side of the roadway. During winter suspension, traffic will open to three lanes of traffic in each direction south of 26th Avenue W. One driving lane will be open north of 26th Avenue W. and utilize the existing Diversion Bridge in each direction.
Scope of work for project segments:
This project work will be between 2018 – 2019 construction seasons, and be in three segments:
Segment 1: 13th Avenue W. to Beaton Drive
- Construction Schedule: 2018
- Proposed Improvement: Five-lane section that includes two lanes in each direction and a center left turn lane.
Segment 2: Beaton Drive to 32nd Avenue W
- Construction Schedule: 2018 & 2019
- Proposed Improvement: Six-lane section with a raised median and offset left turn-lanes and a new bridge over the Sheyenne Diversion.
Segment 3: 32nd Avenue W. to 40th Avenue W.
- Construction Schedule: 2019
- Estimated Construction Cost: $15.3 million
- Proposed Improvements: Four-lane section with a raised median and offset left-turn lanes.
